Chemicals under the Toxic Substances Control Act (TSCA)

Chemicals can be found in many of the products we use in our everyday lives. Some chemicals pose risks to humans and the environment. Under the Toxic Substances Control Act (TSCA) and the Pollution Prevention Act, EPA evaluates potential risks from new and existing chemicals and finds ways to prevent or reduce pollution before it gets into the environment. Use this site to get information on chemicals and their regulation under TSCA, on ways to prevent and reduce pollution, and on safer chemicals, products and practices.
